Barcarena is a Brazilian municipality in the state of Pará adjacent the Tocantins River.

[5] They city and port is developing as a major transshipping port that takes goods for international export linked by rail from nearby inland ports, from all over Brazil, speeding up shipment and reducing time and costs as opposed to traditional megaports in the Southeast.

[citation needed] On October 6, 2015, the livestock vessel "MV Haidar" capsized in the Vila do Conde port due to an unsuccessful turning maneuver.

Fuel and oil seeped from the wreck into the water and contaminated the Pará river and surrounding beaches, which deprived many local fisher families of their livelihood.

[8] Since the removal of the oil slick proved to be complicated, and no consensus regarding responsibility and suitable cleanup efforts could be reached, hundreds of carcasses rotted at the beach and inside the shipwreck for months – a huge burden on the fishery and tourism of the region.
